This was already discussed many times, and sadly it looks like a limitation we are not able to overcome.

Hi Maru, I just wanted to say I've been playing around with Hair and Fur and figured out how to get the texture showing through. I've just posted a tutorial on youtube showing how to do it. I hope it helps some people with similar issues. Here's the link:

360p? Do you have version with slightly more reasonable resolution?

Hi Romullus, I uploaded at 2640 by 1440 - I guess it's taking a little while longer than usual for youtube to process it.

Best, Tom

YouTube state:

When you upload a video, it will initially be processed in low resolution. This helps the video to upload faster. Once your upload has been completed, your video will be available to stream in low resolution, usually 360p, on a wide variety of devices.

Higher resolutions, such as 4K or 1080p, can take more time to process. While this happens, your video may appear to be missing high-quality options, such as 4K or 1080p, for several hours. Once high-resolution processing is finished, higher resolutions will be available on your video.

Thanks, i will wait for YT to process the video then. Does this method works only on planar objects, or with any object?

Hi Romullus,

So, I've just checked and it's now at 1920 x 1080.

It works on any object, I figured it out while trying to get it to work on a cat I was putting in a scene. It will copy whatever mapping you have on the base object, so as long as that's correct, all good.

Here's how the cat looks. 

Best, Tom

Sorry to disappoint you, but you didn't discovered anything new. This method is well known and was discussed many times on the forum. It's a workaround, but very poor one. The problem is, that you're not using Corona hair material for this and hair rendering quality is mediocre - you had to extensively use curves and still got nowhere near to the rich colours of source bitmap.

Hah, I was hoping to have watched a tutorial that would change the fate of humanity, but sadly it's not the case. :)

Check out the attached screenshot (which is a screen capture from your tutorial).

Fun fact: even Arnold doesn't support this (which is kinda funny since both Hair and Fur and Arnold are officially parts of 3ds Max, developed by the same company). You need to use some black magic to make it work: https://veda3d.com/arnold-with-hair-and-fur-modifier/

Hi Maru and Romullus, Okay, well understood, yeah it doesn't change the world. I was using output and colour correction to adjust it, it might not quite match the source but it gets pretty close. And you're right, I didn't use Corona Hair material - that would have been nice. :)

That's an interesting fact about Arnold too. It's very similar.

Just to reiterate what has already been said, the only workaround - which itself is not a production-ready solution - is to pipe whatever bitmap is being used to shade the base surface into the tip and root color?

The video from leon51 claims that the Custom Shader (apply shader) option does not work. Is that verified as of Corona 6 RC1?
